asterisk users - Feb 2009 - receive fax problem

Hi:


I want to receive a fax with an E1 link connected to A102d card from a
fax machine,but after dialling the phone number, it connects then will
be busy.In fact asterisk can't detect the fax.These are zapata.conf,
extensions.conf filels and debug in console:





extensions.conf:


[from-pstn]


exten => 9711315,1,Answer()

exten => 9711315,2,Wait(10)

exten => fax,1,SetVar(FAXFILE=/tmp/test.tif)


exten => fax,2,rxfax(FAXFILE)


9711315 is E1  number.





zapata.conf


[channels]


context=default


usecallerid=yes


hidecallerid=no


callwaiting=yes


usecallingpres=yes


callwaitingcallerid=yes


threewaycalling=yes


transfer=yes


canpark=yes


cancallforward=yes


callreturn=yes


echocancel=yes


echocancelwhenbridged=yes


faxdetect=from-pstn


relaxdtmf=yes


rxgain=0.0


txgain=0.0


group=1


callgroup=1


pickupgroup=1


immediate=no





;Sangoma A102 port 1 [slot:6 bus:1 span:1] <wanpipe1>


switchtype=national


context=from-pstn


group=0


signalling=pri_cpe


channel =>1-15,17-31





-- Executing [9711315 at from-pstn:1] Answer("Zap/6-1", "")
in new stack


    -- Accepting call from '3318545' to '9711315' on channel
0/6, span 1


  == Auto fallthrough, channel 'Zap/6-1' status is 'UNKNOWN'


    -- Hungup 'Zap/6-1'





I've installed spandsp and app_rxfax.


I'd appreciate any help and idea.

Why on earth are you waiting TEN seconds to actually receive the fax?
Have you tried ripping that out of your dialplan?

My guess is the sending fax is giving up and closing the connection,
after waiting TEN seconds for a response. If it does this repeatedly
(and it would), the sending fax will output that it couldn't connect /
which it usually calls busy, but it never truly gets a traditional
busy signal. At least that's the output if you do this to my
traditional analog fax machine.

If you want to confirm my theory, you can use the txfax module to fax
yourself from asterisk, and you should have the same problem.

How about which version of Asterisk you're running?
The integrated asterisk app_fax is very, very good in 1.6. I had a lot
of problems with fax in 1.4; all of those problems were solved with my
upgrade to app_fax and 1.6.
